7 reasons to be alarmed by record-setting levels of CO2

By Joe Romm, Climate Progress, June 2017:  Trump puts humanity back on track to CO2 levels not seen since it was 5° to 10°F warmer and seas were 75 to 120 feet higher.   Despite the best efforts of the Trump administration to ignore or contradict scientific reality, carbon dioxide levels continue to soar far outside the bounds of what Homo …

How scientific causation came to be solidified in the tobacco use vs. lung cancer death rates era, relevance to climate skeptics now

By Seth Miller, see Newsfeed for the whole article, June 2017 Data credit: cancer.org, original image slightly reformatted by me in Tableau Long before research exposed evidence that humans cause global warming, science made another sensational claim — that smoking caused lung cancer.  That case has been proven beyond doubt. But there is a science story from this era that is mostly forgotten: The battle …

David Suzuki: Not looking away…We can and must stop dramatically cut down on our use of fossil fuels and plastics

By David Suzuki, EcoWatch, 24 May 2017 People who deny that humans are wreaking havoc on the planet’s life-support systems astound me. When confronted with the obvious damage we’re doing to the biosphere—from climate change to water and air pollution to swirling plastic patches in the oceans—some dismiss the reality or employ logical fallacies to discredit the messengers.  It’s one …

Enabling better planning for droughts in Africa

University of Exeter. “Summer rainfall in vulnerable African region can be predicted.” ScienceDaily. ScienceDaily, 25 May 2017. www.sciencedaily.com/releases/2017/05/170525085109.htm Summer rainfall in one of the world’s most drought-prone regions can now be predicted months or years in advance, climate scientists at the Met Office and the University of Exeter say. The Sahel region of Africa — a strip across the southern …

Allergy, oak pollen and ragweed seasons growing with climate change

More children could wind up in hospital emergency rooms suffering from allergy-induced asthma if greenhouse gas emissions continue to rise and cause longer oak pollen seasons, according to a new study. The new research finds that if greenhouse gas emissions continue to increase through the end of this century, the oak pollen season in some areas could extend by up …

Declining precipitation in Colorado River Basin worsened by rising temperatures

Scientists found that another factor affected the runoff ratio: temperature. Over the last few centuries, the runoff ratio was reduced when temperatures were warmer. And the influence of temperature strengthened during drier years: When the snowpack was shallow, warm temperatures reduced the runoff ratio more than when the snowpack was deep, further exacerbating drought conditions. The low runoff ratios seen …

New research finds that most previous estimates for sea level rise were too conservative, while visualizations show what U.S. cities may look like by 2100

 On Common Dreams, by Nika Knight, April 2017  President Donald Trump’s Mar-a-Lago resort would be completely drowned in the most extreme scenario for sea level rise. (Image: Climate Central) A new report shows that many previous estimates of global sea level rise by 2100 were far too conservative, the Washington Post reported Thursday, and the research comes as new maps and …

On a 100-year timescale, dams produce more methane than rice plantations & biomass burning, + push people off land and livelihood

ScienceDaily, 17 May 2017 Water reservoirs created by damming rivers could have significant impacts on the world’s carbon cycle and climate system that aren’t being accounted for, a new study concludes. The study, conducted by researchers at the University of Waterloo and the Université libre de Bruxelles, appears in Nature Communications. It found that human-made dam reservoirs trap nearly one-fifth …

Agriculture begins to tackle its role in climate change

After years of being off the table in climate talks, agriculture is now being considered widely by countries trying to reach their Paris emissions cuts pledges. By Georgina Gustin, Inside Climate News 4 Jan 2017 Farming in places like drought-plagued California is clearly impacted by climate change, but it can also play a role in slowing global warming, many countries …
